Unit Identification Switch/LED
A Unit Identifier switch (UID) and a
rear UID LED indicator (LED3) are
located next to LAN ports on the back
of the chassis. When the user pushes
the rear UID switch, the rear UID LED
(LED3) will be turned on. Push the
UID switch again to turn off the LED
indicator. The UID switch provides
easy identification of a system unit
that may be in need of service. See
the tables on the right for more infor-
mation. For more information on the
UID switch and LED indications, refer
to Page 2-18.
